Question

void print(part *item, int part_count) {
    int i=0;

    for (i=0; i<part_count; i++) {
       printf("Item number: %d\n", i + 1);
       printf("Item name: %s\n", item[i].name);
       printf("Item price: $%f\n", item[i].price);
       printf("Item quantity: %d\n", item[i].quantity);
    }
}

i want to print an array of structs created with a different function. I have looked but have yet to find a different way to print them or what i am doing wrong in the print statements. My program compiles but crashes upon running.

ok well it is good to know the problem is not within these statements. That was frustrating me. here is the add function.

void add(part *item, int *part_count)
 {
      if (!item)
      {
         item = malloc(sizeof(part));
      }

      item = realloc(item, sizeof(part) * *part_count + 1);

      item[*part_count].name = malloc(sizeof(char)*64); // max of 64 characters

      printf("Please enter item name: ");
      scanf("%65s", item[*part_count].name);

      printf("Please enter item price: ");
      scanf("%f", &item[*part_count].price);

      printf("Please enter item quantity: ");
      scanf("%d", &item[*part_count].quantity);

      *part_count = *part_count+ 1;
 }

void add(part **item, int *part_count)
{
  char temp[100];

  if (!(*item)){
   //printf("first alloc\n");
       *item = malloc(sizeof(part)*3);
  }
  else if (*part_count>= 3){
  //printf("realloc\n");
      *item = realloc(*item, sizeof(part) * (*part_count + 1));
  }

  item[0][*part_count].name = malloc(sizeof(char)*100); // max of 100 characters

  printf("Please enter item name: \n");
  fgets(temp, 100, stdin);     
  strcpy(item[0][*part_count].name, temp);      


  printf("Please enter item price: \n");
  fgets(temp, 100, stdin);
  sscanf(temp, "%f", &item[0][*part_count].price);      


  printf("Please enter item quantity: \n");
  fgets(temp, 100, stdin);
  sscanf(temp, "%d", &item[0][*part_count].quantity);   


  *part_count = *part_count+ 1;
}

This ended up doing it. Not sure if using a **struct was necessary but was the only method I could get working.
